Acura hopes its new souped up TSX model will be a hit with youthful drivers when sales of the V-6 model begin this summer.

The sport sedan, which debuted Wednesday at the Chicago Auto Show, is equipped with a 280-horsepower 3.5-liter engine, 18-inch split five-spoke aluminum wheels, double-wishbone front and multilink rear suspension system, and standard leather interior.

It's targeted at "youthful buyers who want a performance-oriented sports sedan in a more personal size," according to executives who say the vehicle will fill a niche between the four-cylinder TSX and the luxury TL sedan.
